The text had cunning hardspaces in it so that the *HELP text lines up nicely using OS_PrettyPrint, but not taking into account that internationalised syntax errors don't use OS_PrettyPrint so output VDU31,31,31 and jumped all over the place.
Syntax message rephrased to fit on one line.
Syntax and help for *TV cleared up since the help text contained all the syntax information.
Spotted 2 wasted instructions in Oscli.s while investigating, added some comments too.

Version 5.35, 4.79.2.137. Tagged as 'Kernel-5_35-4_79_2_137'

Implement OS_ConvertVariform, internally the other conversions now just call it.
Add tester for Variform to 'Dev'.
Made block copy weirdness for XScale dependent on XScale arch flag.

Version 5.35, 4.79.2.126. Tagged as 'Kernel-5_35-4_79_2_126'

Detail:
  Lots of changes since last version, at least the following:
  * Updated OS timestamp, removed alpha status
  * Negative INKEY OS version changed to &AA
  * GraphicsV is now alocated vector number &2A
  * ROM moved up to &FC000000
  * Max application slot increased to 512 Mbytes (for now)
  * Max size of RMA increased to 256 Mbytes
  * RMA is now first-created dynamic area (so it gets lowest address after
    top of application slot)
  * OS_Memory 10 reimplemeted
  * New OS_ReadSysInfo 6 values 18-22 added
  * OS_ReadSysInfo 8 gains flag bit to indicate soft power-off
  * Misc internal top-bit-set-address fixes
  * *ChangeDynamicArea can take sizes in megabytes or gigabytes
  * Magic word "&off" in R0 passed to OS_Reset powers down if possible
  * Added acceleration: block copy; CLS; text window scroll up; rectangle
    fill
  * Disabled LED flashing in page mode (liable to crash)
  * Masked sprite plot and VDU 5 text avoids reading the screen if possible
  * Framestore made USR mode accessible
  * Fix for VDU 5,127 bug - now relies on font definitions being in extreme
    quarters of memory, rather than bottom half
  * Allocated 64-bit OS_Convert... SWIs
  * IIC errors use allocated error numbers
  * Looks for Dallas RTC before Philips RTC because we're using a Philips
    NVRAM device with the same ID
  * Fix to bug that meant the oscillator in the Dallas RTC wasn't enabled
  * Default mouse type (USB) changed to allocated number
  * Ram disc max size increased to 128 Mbytes (Ursula merge) and made
    cacheable for StrongARMs (not XScale)
  * Branch through zero handler now works in USR mode, by use of a
    trampoline in the system stack to allow PC-relative register storage
  * Address exception handler changed to not use 0 as workspace
  * OS_Memory 13 extended to allow specification of cacheability and access
    privileges
  * Added OS_Memory 16 to return important memory addresses
  * RISCOS_MapInIO() takes cacheable flag in bit 3, access permissions in
    bits 10 and 11, doubly-mapped flag in bit 20, and access permissions
    specified flag in bit 21
  * Bug fix in last version for application abort handlers didn't quite
    work; register shuffle required
  * "Module is not 32-bit compatible" error now reports the module name
  * Default configured language changed from 10 to 11 (now Desktop again)

Version 5.35, 4.79.2.51. Tagged as 'Kernel-5_35-4_79_2_51'

Version 5.35, 4.79.2.48. Tagged as 'Kernel-5_35-4_79_2_48'

More stuff. Up to the desktop now; cache on, working keyboard. Some source restructuring to start to make splitting it up into several object files more feasible.

Detail:
  RiscPC-like (UserIF = Morris4) and Ursula-like (UserIF=Ursula)
  builds of the Kernel have their messages in a subdirectory while
  more generic builds use the main Messages file.

  The main file has had the RISC OS User Guide references removed
  and the "There is not enough memory" message changed to the more
  correct "Memory can not be moved".
Admin:
  Partially tested. Fixed STB-400 fault #1479

Version 5.29. Tagged as 'Kernel-5_29'

Details:
  The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
  set to TRUE.
  If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
  although some internal changes have taken place to minimise compile
  switches between the two cases. See Docs.32bit for more technical info.

  The hardest part was the flood-fill...

Other changes:
  Pointer shape changes now take place on the next VSync, rather than actually
  WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
  down by 5% now :)

  Lots of really crusty pre-IOMD code removed.

Admin:
  Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
  will need to see a lot of use to iron out difficulties. I'd like anyone who
  has a non-frozen project to at least attempt using this Kernel.

Version 5.23. Tagged as 'Kernel-5_23'

CPU type messages internationalised.
"Unknown OS_PlatformFeatures reason code" internationalised.
RunningOnEmul flag tweaked.
MorrisIDString conditional removed.
New modules added to SWI list at the end of the chain, on grounds that
the first-registered modules are probably more important.
*ChangeDynamicArea moved into UtilityModule from TaskManager.

Version 4.65. Tagged as 'Kernel-4_65'

Bandwidth limit for 7500FE fixed.
RO371Timings flag set to :LNOT:STB

Version 4.64. Tagged as 'Kernel-4_64'
