testsuite support - make-parser - Trap PEG syntax errors and abort properly with readable message
Fixed bad assert, range was off-by-one.
Added lots of test cases going over characters special to PEG, Tcl, and C. Currently mainly failing due to bogus handling in the various generators. The layers of quoting need some sorting.
pt::pe - Added constructors for explicit char-classes and strings. Version bumped to 1.0.2.
char - Reworked the internals to be more useful. Fixed the internals docs. Added testsuite. Version bumped to 1.0.1.
pt::rdengine (tcl) - Tweaks to the err msg code for clarity.
pt::util - Expansion of error details for readability added, plus fusion of terminals and char-sets into single char-set.
pt::pgen test cases for error handling updated and tweaked. Pass for all Tcl backends. Fail for the generated C backend. To be fixed.
