I was trying to match just the top-level bin and pkg directories, and I put the
final slash in because 'git help gitignore' says:
o If the pattern does not contain a slash /, Git treats it as a shell
glob pattern and checks for a match against the pathname relative
to the location of the .gitignore file (relative to the toplevel of
the work tree if not from a .gitignore file).
o Otherwise, Git treats the pattern as a shell glob suitable for
consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in
the pattern will not match a / in the pathname. For example,
"Documentation/*.html" matches "Documentation/git.html" but not
"Documentation/ppc/ppc.html" or
"tools/perf/Documentation/perf.html".
Putting a trailing slash was my way of opting in to the "rooted path" semantics
without looking different from the surrounding rooted paths like "src/go/build/zcgo.go".
But HA HA GIT FOOLED YOU! above those two bullets the docs say:
o If the pattern ends with a slash, it is removed for the purpose of
the following description, ...
Change all the patterns to use a leading slash for "rooted" behavior.
This bit me earlier today because I had a perfectly reasonable source
code directory go/src/cmd/go/testdata/src/empty/pkg that was
not added by 'git add empty'.
