src/bin/sh: input.c input.h parser.c
Log Message:
Deal with \newline line continuations more correctly.
They can occur anywhere (*anywhere*) not only where it
happens to be convenient to the parser...
This fix from FreeBSD (thanks again folks).
To make this work, pushstring()'s signature needed to change to allow a
const char * as its string arg, which meant sprinkling some const other
places for a brighter appearance (and handling fallout).
All this because I wanted to see what number would come from
echo $\
{\
L\
I\
N\
E\
N\
O\
}
and was surprised at the result! That works now...
The bug would also affect stuff like
true &\
& false
and all kinds of other uses where the \newline occurred in the
"wrong" place.
An ATF test for sh syntax is coming... (sometime.)
