* * generic/tclCompExpr.c: Added a "parseOnly" flag argument todgp2007-07-111-49/+29
| | | | | | | | | | | ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an end goal of filling a Tcl_Parse with Tcl_Tokens representing the parsed expression, or TclCompileExpr() with the goal of compiling and executing the expression. In the latter case, more aggressive conversion of QUOTED and BRACED lexeme to literals is done. In the former case, all such conversion is avoided, since Tcl_Token production would revert it anyway. This enables simplifications to the GenerateTokensForLiteral() routine as well.

Also, converted precedence definitions and lookup tables to use symbolic constants instead of raw number for improved readability, and continued extending/improving/correcting comments.
