* warn_summary (longLineFilter): New shell function to encapsulate
this functionality. It is off by default, only active if -llf
flag is specified.
(subdirectoryFilter): Fix bug in filtering which made some
subdirectory warnings erroneously appear in the toplevel set.
(stageNfilter): Renamed from `stageNwarns'. Updated to collect
warnings from stage1 as well as stage0, which means warnings from
outside the bootstrap directory. Eg, the libraries, etc.
(warningFilter): New shell function to encapsulate this
functionality.
(keywordFilter): New shell function to encapsulate this
functionality.
Store data in a temp file rather than calculating it 3x. Arrange
to remove it on exit and signals.
Add -pass/-wpass flags to do "pass through" (i.e. manual
inspection) of bootstrap output from a particular stageN as well
as language subdirs.
Add better comments/documentation.

* warn_summary (subdirectoryFilter): New shell function to
optionally filter in/out gcc subdirectories when summarizing
warnings. Add new flags to support subdirectory filtering.
Also, ensure the bootstrap stage is a number. Add some more C
keywords that are preserved in the "warning type" summary and
tighten up the "arg ???" regexp.
