option --init-missing of pybabel update should also create the corresponding directory #1139
Description
I use the option --init-missing of pybabel update to avoid redundant pybabel init command. However, this option only creates the *.po file, and will fail if the target directory ([locale]/LC_MESSAGES) does not exist yet:
creating catalog .\en_US\LC_MESSAGES\strings.po based on strings.pot

FileNotFoundError: [Errno 2] No such file or directory: '.\\en_US\\LC_MESSAGES\\strings.po'This behavior makes the option less useful. I suggest invoke os.makedirs in UpdateCatalog.finalize_options, just like in InitCatalog.finalize_options:
babel/babel/messages/frontend.py
Lines 629 to 630 in f91754b
but with extra
exist_ok=True argument, as the directory may already exist for the update command.
Or it might be better to reuse the logic in InitCatalog.
