Better fix for parser "bug" in pmars 0.9.2

[newton]

This is a better pmars patch to correctly parse \ in comments...
(should also apply to pmars versions 0.8.6, 0.9.2-5 etc)

In asm.c change it to something like...

----- etc -----
/*
* Read characters until newline or EOF encountered. newline is
* excluded. Need to be non-strict boolean evaluation
*/
*buf = '\0';
i = 0; /* pointer to line buffer start */
// fixes by WTN 2/23/09 to make paperone marcia13 jackinthebox
// and other warriors that use \ in comments work properly.
int commentfound = FALSE;
do {
if (fgets(buf + i, MAXALLCHAR - i, infp)) {
for (; buf[i]; i++) {
if (buf[i] == ';') commentfound = TRUE;
if (buf[i] == '\n' || buf[i] == '\r')
break;
}
buf[i] = 0;
if (buf[i - 1] == '\\' && commentfound == FALSE) {
/* line continued */
// end WTN changes
conLine = TRUE;
buf[--i] = 0; /* reset */
} else
conLine = FALSE;
----- etc -----

If a line contains ";" the \ at the end of a line is
ignored, otherwise used as a continuation character.
Briefly tested, seems to work, but others should validate
these changes, for I'm not really a C programmer, just a
user who hacks C programs into submission as needed.
