bootstrap: .gitignore files created by autopoint, libtool I ran into this problem when bootstrapping the latest diffutils. After './bootstrap', 'git status' reported lots of untracked files m4/codeset.m4, m4/gettext.m4, etc. These files were created by autopoint and do not need to be version-controlled. * build-aux/bootstrap: Put into .gitignore the files that autopoint and libtool create, by keeping track of files that exist after but not before these programs are run. (version_controlled_file): Move up. 2nd arg is now full file name, not base name; this is more convenient. Put CVS at the end, as it's now somewhat deprecated.
