The script was returning success unless it failed on the last file.
This went unnoticed because sc_prohibit_long_lines forbids lines
longer than 90 characters in .arg[sv] files.
Commit c9c03ea stopped creating an intermediate file during syntax-check
to save on execution time. It also switched to outputting the whole
incorrectly wrapped file instead of a diff needed to fix it.
Feed the newly wrapped file to diff via a pipe.
Note that fixing it by running test-wrap-argv.pl --in-place or
the unit test with VIR_TEST_REGENERATE_OUTPUT is easier.
This script can already operate on a list of files.
Add a --check parameter to check if multiple files are wrapped
correctly with a single invocation of the script.
We have a list of parameters in @args, that need to be rewrapped
and separated by a space and escaped newline: " \\\n", with the
exception of the last one, which only needs a newline.
Instead of a for cycle, rewrap the individual arguments using map,
and interleave them with escaped newlines by using join.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args
were less than 80 characters.
The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.
This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.
