Uncommented recursive targets in configure.ac (doesn't work with automake <1.13); added --enable-line-pragma=no in ./configure to get rid of #line 314 in generated source files; implemented gab-buffer function gb-re-search-forward so I could add {forward,backward}-word commands; added debug-on-error? variable that will cause program to drop to guile shell if there is an error; a emacsy-ran-undefined-command? flag is captured.
