Rename 'maint/' -> 'maintainer/', for Git's sake Otherwise, Git gets confused by the fact that a directory ('maint') is named like a branch, and forces me to tweak the command line to resolve the ambiguity for it. * maint/: Rename ... * maintainer/: ... like this. * Makefile.am, GNUmakefile: Adjust.
