I frequently use WinMerge, a graphical text file comparision program,
from the bash shell. Occasionally this involves a file in the current
directory vs a file at the end of a path full of spaces and slashes.
If this question had come up yesterday I could have looked at my
history for examples. My recollection is that the rules for expanding
arguments enclosed in single quotes are helpful. Single-quoted
arguments are processed much less by bash than even double-quoted
arguments. A simple example is if you need to put a backslash in an
environment variable, you don't have as many layers to fight if you
use single quotes export regex='search\$'. I also use $(cygpath) in
some fashion to convert the path since WinMerge is not a Cygwin
program. I get the full path to one of the files using tab completion,
and then I modify the path by surrounding it with the necessary
cygpath syntax to convert the path to a Windows path.
