* src/version.h (PEG_LEVEL): Version is 0.1.20.
* src/tree.c (makeInline): Inline nodes remember their parent rule.
Replace "$$" in inline actions with "__".
* src/tree.h (struct Inline): Inline nodes remember their parent rule.
* src/leg.leg (main): Filenames on WIN32 have \ changed to /, keeping
#line directives happy.
(main): Don't print #line directives for headers if nolineFlag is set.
* src/compile.c (allocateVariables): Separated from defineVariables.
(Node_compile_c_ko): Allocates and sets local variables during parse.
(Rule_compile_c2): Generate yyEnter and yyLeave if rule has variables.
(preamble): Macros yyEnter and yyLeave manage local variable space on
stack during parsing.
* Makefile (testleg): Quickly tests local changes.

* src/version.h (PEG_LEVEL): Version 0.1.19.
* src/compile.c: Allow re-entrant parsing.
Macro YYPARSEFROM_R names the function yyparsefrom_r().
yyDone takes second argument, the yythunkpos at which actions start.
yyparsefrom_r saves and restores thunkpos and val state during recursive parse.
yyparsefrom resets thunkpos, val before recursive parse.

* src/version.h (PEG_LEVEL): Version 0.1.18.
* src/tree.h: Rule_compile_c takes nolines argument for option -P.
* src/compile.c, src/peg.c, src/leg.leg (main): Add option -P.
Generate #line directives for all actions.
* src/peg.1: Document option -P.
