3270 version of HELP doubles file contents

[RossPatterson]

If you happen to have HELP files with 8-character filetypes (e.g., ABBREV HELPREXX), the 3720-mode HELP command will display the contents of the file twice. The fix is to, when finding files with a filetype of HELPxyz2, to not generate a 9-character filetype.

HELPFS EXEC U diff via XCOMPARE:

FILE 1    468     'STATE' subcmd ft'2' '*'
FILE 2    468     ft2 = strip(left(ft,7))'2'
FILE 2    469     'STATE' subcmd ft2 '*'

FILE 1    471           'EXECIO * DISKR' subcmd ft'2 * ( FINIS STEM LINES2.'
FILE 2    472           'EXECIO * DISKR' subcmd' ft2 * ( FINIS STEM LINES2.'

There are only 3 files on the VM/CE 1.1.2 MAINT 19D help disk with a filetype of HELPxxx2:

• GCCLIB HELPCMD2
• REXX HELPCMD2
• WELCOME HELPOLD2

All of these appear to be obsolete, and the current VM/CE HELP command isn't able to display them, because they're not reachable via HELP HELPTASK U.
