2013-02-02-16.12.26: src/lib/make-library-glue/patchable-file.pkg: Added convenience fns intron_count, exon_count, get_intron, get_introns, set_intron, set_introns.   src/lib/std/src/io/winix-text-file-for-os.api, src/lib/std/src/io/winix-text-file-for-os--premicrothread.api:  Renamed lines -> as_lines, partly for better greppability, mostly because we will probably wind up with a small family of as_* fns, and this will make the family relationship clearer.
