states:
grog does not parse roff control structures (the "if", "ie", and "el"
requests) nor groff's "while". Thus the input
.if t .PS
.if t .PE
will not, for example, cause grog to infer use of the pic(1) preprocessor.
This may be valid to point out in general, but the specific example is not:
pic will also not recognize those lines as begin and end markers. pic
requires that the .PS and .PE be at the start of the line, without so much as
a space between the dot and the macro name.
Thus, pic will not preprocess lines set off as in the example above, so grog
is actually correct to not output the -p option based on them.
