I can verify this behavior and that removing the CursorHold
autocommand "fixes" the problem. It may be a bug in Vim. I
reported a similar problem with the 7.0b or 7.0c release that did
turn out to be a bug in the event handler.
It's not just mappings that are affected. With the following
settings:
showcmd
notimeout
nottimeout
updatetime=500
and the ctags.vim CursorHold autocommand enabled, if I type a
cursor-movement command (such as 'j') immediately followed by a
double-quote to start a register name, the double-quote briefly
appears in the 'showcmd' area, then disappears with a beep. If I
increase 'updatetime' to 5000 and repeat the experiment, the
double-quote stays for about 5 seconds before disappearing.
It looks to me like an undesirable interaction between processing of
the CursorHold autocommand and processing of commands from the
keyboard. Bram?
I should mention that I'm using the 7.0 release, unpatched. I'm
working on bringing it up to the current patch level, but I'm not
done with that yet.
