A recent edit to a tip includes a claim that having :match in autocmd events leads to severe slow downs due to a memory leak.
The tip has a variety of methods to highlight unwanted spaces, including the following extreme version which attempts to highlight dubious spaces as you type, but NOT highlight a trailing space at the end of a line as you are typing it: highlight ExtraWhitespace ctermbg=red guibg=red match ExtraWhitespace /\s\+$/ autocmd BufWinEnter * match ExtraWhitespace /\s\+$/ autocmd InsertEnter * match ExtraWhitespace /\s\+\%#\@<!$/ autocmd InsertLeave * match ExtraWhitespace /\s\+$/ autocmd BufWinLeave * call clearmatches() The last line was just added with the claim that it is necessary to avoid severe slow downs. I probably won't have an opportunity to check this claim, and there is no indication of what version of Vim was used, but I thought I would mention this in case someone wants to investigate.
