check-code: check for spaces around = for named parameters

run-tests: place the .t shell script next to $TESTTMP and with a useful name --keep can thus keep it around - very convenient for debugging.

tests: fix void and invalid test in test-archive.t An echo statement was missed in the .t-ification in afe19a1bf9d3 so we ended up with invalid sh syntax. But at the same time a continuation line was marked as $ instead of > and we thus added the salt that made the expression valid again.

inotify: don't pass pidfile option to child The child no longer needs it.

cmdutil.service: move pidfile writing to the parent in daemon mode There is a potential race here, which I suspect I've spotted in the wild, where something reads the pid file after the parent exits but before the child has had a chance to write to it. Moving writing the file to the parent causes this to no longer be an issue.

cmdutil.service: move pidfile writing to a local function An upcoming patch will reuse this code.

inotify: add pidfile to parent options An upcoming patch will move pidfile writing from the parent to the child. This means that if the pid file isn't specified on the command-line but is specified as a config option, it needs to be added to the parent's opts dict.

get-with-headers: don't block indefinitely if the server had an internal error If the server had an internal error and returned 500, there's nothing to read, so "response.read()" blocks indefinitely. Only output the response if there's really a response.
