Merge bug fixes into release

[NKID00]

1009 #1188 fixed the date formatting bug in the master branch. However the same bug still exists in the latest release and caused malfunction of my server.

master:

• https://github.com/bottlepy/bottle/blob/f9b1849db4dd724e36a93a1032be592193fba581/bottle.py#L2911-L2912

• https://github.com/bottlepy/bottle/blob/f9b1849db4dd724e36a93a1032be592193fba581/bottle.py#L2913

• https://github.com/bottlepy/bottle/blob/f9b1849db4dd724e36a93a1032be592193fba581/bottle.py#L1888

release-0.12:

• https://github.com/bottlepy/bottle/blob/152219818378926f20a5ee3d339118d7cf50a8f6/bottle.py#L2499-L2500

• https://github.com/bottlepy/bottle/blob/152219818378926f20a5ee3d339118d7cf50a8f6/bottle.py#L2506

• https://github.com/bottlepy/bottle/blob/152219818378926f20a5ee3d339118d7cf50a8f6/bottle.py#L1648

Is it possible to merge these bug fixes (and also other bug fixes which haven't been merged) into the release branch?

Or should I use the master branch in a production-grade server in order to get the bug fixed?

@NKID00 I have been using the master branch for like 4 years now in production.. Never had a problem. Bottle is quite well tested 💪

@oz123 Thanks. The server using the master branch is working just fine now.
