This concept is quite similar to my idea but instead of putting all .c
files I want to be processed by save hook into one directory and
running a hook that checks if a particular file actually is in a given
directory you suggest to put `.dir-locals.el' file in every single
directory with .c files. Seems quite error-prone and tiring.

I don't think this is what I am looking for. The problem is I don't to
run *any* save hooks on most files but only on selected ones, these
ones that belong to me or ones that I am sure about coding rules.

ATM I start to think that save hooks should be disabled by default and
activated manually. Otherwise there is no benefit from them - why
would I need to, let's say, change all tabs to spaces in a project I
touched for the first time or was given by e-mail and need to send
back?
