style: kill ersatz if-else ternary operators
Although Python supports `X = Y if COND else Z`, this was only
introduced in Python 2.5. Since we have to support Python 2.4, it was
a very common thing to write instead `X = COND and Y or Z`, which is a
bit obscure at a glance. It requires some intricate knowledge of
Python to understand how to parse these one-liners.
We change instead all of these one-liners to 4-liners. This was
executed with the following perlism:
find -name "*.py" -exec perl -pi -e 's,(\s*)([\.\w]+) = \(?(\S+)\s+and\s+(\S*)\)?\s+or\s+(\S*)$,$1if $3:\n$1 $2 = $4\n$1else:\n$1 $2 = $5,' {} \;
I tweaked the following cases from the automatic Perl output:
prev = (parents and parents[0]) or nullid
port = (use_ssl and 443 or 80)
cwd = (pats and repo.getcwd()) or ''
rename = fctx and webutil.renamelink(fctx) or []
ctx = fctx and fctx or ctx
self.base = (mapfile and os.path.dirname(mapfile)) or ''
I also added some newlines wherever they seemd appropriate for readability
There are probably a few ersatz ternary operators still in the code
somewhere, lurking away from the power of a simple regex.
