*.eps and *.svg .gitignore patterns match files in repo

[markdblackwell]

Per https://www.kernel.org/pub/software/scm/git/docs/gitignore.html

"A gitignore file specifies intentionally untracked files that Git should
ignore. Files already tracked by Git are not affected"

I misspoke. More accurately:

If a file is *already* in the repository, then its name matching a
.gitignore pattern won't cause Git to ignore changes to it; Git still will
commit its changes easily.

Only *new* files which match a .gitignore pattern will be ignored, silently.

If these particular new files have names (or extensions, or path fragments,
depending on the particular .gitignore pattern) similar to files present in
the repository, then this is confusing.

In order to make the relevant patterns more accurately discriminatory, we
might identify the programs (that we use) which generate noise files (i.e.,
files we want to exclude from the repository) of these kinds, and in which
directories. Does anybody know?

Otherwise, we should try removing these particular .gitignore patterns, and
see whether our procedures still generate any of these unwanted files—and in
which directories. Then (obviously) we can reinstate the patterns, and make
them more discriminatory.

Here's what Git blame says is the latest commit which changed the relevant
lines in /.gitignore:

$ git blame .gitignore

915e0d52 (Jan Nieuwenhuizen 2006-12-05 14:54:32 +0100  2) *-midi.ly
915e0d52 (Jan Nieuwenhuizen 2006-12-05 14:54:32 +0100  9) *.eps
915e0d52 (Jan Nieuwenhuizen 2006-12-05 14:54:32 +0100 26) *.svg
