Hi all,

I’ve had some occasions where I’ve been editing multiple files at once, and for some reason some of the files did not get syntax highlighting turned on.  I could never really pinpoint the circumstances until today when I decided to use a binary search approach to track down what it might be.

The problem occurs with 7.2.293 that I’ve compiled as well as stock 7.2 with the following 3-line .vimrc:

set hidden

filetype on

syntax on

And then invoke Vim as follows in a directory that has several .c files (it seems you could use any :bufdo command here, this is just an example):

vim -c “bufdo normal gg” *.c

The problem I see is that the first and last buffers have syntax highlighting, but all the intermediate buffers do not.  For example, if there are 10 .c files, then only buffers 1 and 10 will have syntax highlighting.

There are several different components interacting in this scenario, so I’m not sure which are actually necessary to cause the problem, and which are just there to expose the problem.  I suspect the problem may be in the interaction between ‘hidden’ and :bufdo, since both of those involve buffers.

P.S.  I actually don’t remember why I set ‘hidden’ in my .vimrc, it’s just been that way for so long!
