Make 4OS2 more Unix-like (sane forward slash handling; sane quoting & escapes, etc.)

[Lewis Rosenthal]

It's great that 4OS2 can recognize slashes as path separators. However, when using autocomplete, for example, starting a path with "/" should then trigger recognition and subsequent <tab> entries should insert "/" vs "\".

Example:

[c:\]cd /somedir<tab>

results in:

[c:\]cd /somedir\

instead of:

[c:\]cd /somedir/

Example #2 - recognize "-" as a substitute for "/" when passing options to commands:

[c:\]xcopy -?

results in:

0 file(s) copied.

instead of:

Use the XCOPY command to selectively copy groups of files.
Syntax: XCOPY [drive:][path] filename [drive:][path] [...]

Further examples:

[j:\]copy os2web m:\Apollo\2013-07-04\j\OS2WEB /s /e /h /q /u
SYS0003: The system cannot find the path specified. "M:\Apollo\2013-07-04\j\OS2W
EB\Mozilla\SeaMonkey\Profiles\4h0tldty.default\ImapMail\imap.gmail.com\[Gmail].s
bd"

EB\Mozilla\SeaMonkey\Profiles\4h0tldty.default\Mail\mail.2rosenthals.com\Vendors
 & Service Providers.sbd\NAS (formerly Ardent; CAIS).sbd"

Apparently, in one case, "[" is breaking the expansion, in spite of the quotes, and in the other, the ";" (not the "(") appears to be the stumbling block.
