Log Message:
Open code the validity test & copy of the character class name in
a bracket expression in a pattern (ie: [[:THISNAME:]]).   Previously
the code used strspn() to look for invalid chars in the name, and
then memcpy(), now we do the test and copy a character at a time.
This might, or might not, be faster, but it now correctly handles
\ quoted characters in the name (' and " quoting were already
dealt with, \ was too in an earlier version, but when the \ handling
changes were made, this piece of code broke).

Not exactly a vital bug fix (who writes [[:\alpha:]] or similar?)
but it should work correctly regardless of how obscure the usage is.
