The following are the changes in this release:
Converted all ASCII tabs to ASCII spaces using a 8 character
tab stop, for all files, except for all Makefiles (plus rpm.mk).
The command `git diff -w` reports no changes. There is no
functionality change in calc: only ASCII tabs to ASCII spaces.
Fixed trailblank. It was pruning . in its find search.
Added check for ASCII tabs is non-Makefiles.
This version will form the basis for the calc v2 to calc v3 fork.
