Cygwin and short windows filenames (Was RE: Open bash at the currentexplorer directory?)

[Igor Pechtchanski <pechtcha at cs dot nyu dot edu>]

Gunnar,

You're right, this is a problem.  Cygwin should be able to handle windows
short form of directory names just as well as the long ones...  For some
reason it doesn't ('cd /cygdrive/c/PROGRA~1' results in "cd:
/cygdrive/c/PROGRA~1: No such file or directory").  This is happening in
most shells (sh, bash, tcsh), so I'm assuming it's a 'chdir()' problem.
This only seems to happen if "check_case:strict" is part of $CYGWIN.
Passing a short windows filename to other programs, e.g., vi, also fails
with check_case:strict and succeeds with check_case:relaxed/adjust.

I used a pair of short programs to test chdir(): cdtest.c and
cdtestnative.c.  cdtest.c called chdir(), and cdtestnative.c called
SetCurrentDirectory(), which chdir() uses internally.  Both "cdtest
'c:\Program Files'" and "cdtestnative 'c:\Program Files'" succeeded.
"cdtest 'c:\PROGRA~1'" failed, whereas "cdtestnative 'c:\PROGRA~1'"
succeeded.  I'm attaching both programs, and the strace output for three
runs of cdtest: "cdtest 'c:\Program Files'" (cdtest_ProgramFiles.strace),
"cdtest 'c:\PROGRA~1'" (cdtest_PROGRA~1.strace), and "cdtest 'c:\PROGRA~1'"
with check_case:adjust in effect (cdtest_PROGRA~1_adjust.strace).

>From the output, it looks like conv_to_win32_path() is not behaving
correctly with short names.  Can someone check on this?
