What about -s?
As i hinted in my previous message, the flags handling in cygpath is
inconsistent.
For example:
*) "-t mixed" and "-m" are treated differently wrt the "system" options.
*) You can have "-l" and "-s" in effect at the same time (which
literally means "convert to a short path and then convert back to a
long path" -- maybe this is useful, eg it does filename case
normalization, and checks to see if the file exists, but it seems odd)
*) Options read from a file with "-o" are processed differently to
options on the commandline (for example, in that case the most recent
of -s and -l takes precedence, rather than both in effect at once.)
Also, in case you missed it some other bug causes "-l" with a
nonexistent file to five a corrupted output
