let buffers = []
Some improvements for the buflist implementation This should make the buflist algorithm faster. Also there is an alternative implementation in branch 535 available, which avoids looping over the complete range, I'll stay with the current approach, as it does not depend on BufAdd/BufDelete autocommands. details: instead of testing for buflisted() and bufexists() we only test for buflisted() because, this also tests for the existence of the buffer. Also instead of a second loop of the exclude patterns, we'll join all of them together with '\|' and check if they match the current buffer. The rest of the conditions have been joined into a single condition. This together made up an improvement of Orig: FUNCTION airline#extensions#tabline#buflist#list() Called 94 times Total time: 0.267305 Self time: 0.267305 New: FUNCTION airline#extensions#tabline#buflist#list() Called 85 times Total time: 0.124572 Self time: 0.124572

for nr in list
Changed bufloaded back to buflisted The last PR (#2522) caused some issues for me, and the author @KSR-Yasuda suggested that this change could be the culprit. `__CtrlSF__` and `[No Name]` tabs appearing, and adding them to `airline#extensions#tabline#ignore_bufadd_pat` just made the whole tabline disappear. I also use the Startify plugin with session saving, and found that when restoring a session, the tabs would no longer appear until I had visited a buffer again, whereas beforehand they would load up a soon as I opened Vim. So I commented out my entire vimrc, and could reproduce this issue by opening an existing session with `vim -S mysession`. Without this fix, only a single buffer from the session is shown in the tabline. I'm using regular Vim, version 8.2 on MacOS 12.3.1.
