compute regexps for datafiles for performance
improve perf by using optimized datafile regexps
ignoramus-boring-p up to 4x faster
only compare one-by-one for exact hit if regexp matches
don't pre-compute a case-folded filename (perf)
let the optimzed regexp do most of the work.  compare-strings
is slower, but only called in case of hit.
allow passing an explicit basename for perf
allow marking files as expanded for perf

Emacs 22 broken in travis
allow_failures is not working?
re-enable Emacs 22 Travis build
update libs for Emacs 22 Travis build
- needs i386-specific versions of many packages
Travis: always do "apt-get -f install"
just in case, to fix broken packages
Emacs 22 Travis: emacs22-bin-common needs force
on dependencies -- it appears to misread the architecture of the
emacs22-common package
readability: re-org flags
