i would have assumed the same but, i swear, that situation is not
addressed clearly in the man page. one would think this interpretation
would be the correct one since it's so *obviously* the most useful
interpretation, and i would have expected to see it used frequently in
the kernel source tree.
oddly, in all of the kernel .gitignore files, that occurs only once
in tools/thermal/tmon/.gitignore, whose entire contents are:
/tmon
which represents the executable generated by building that tool, so
that makes perfect sense, but sure doesn't explain why there is not a
single other occurrence of that structure anywhere in the tree. weird.
the more i read the man page, the confuseder i get.
