Shell overquotation

[Akim Demaille]

Well, sure this is debatable, but since that's the style promoted and
used by Autoconf, since it's lighter, since (but I know this argument
is just MHO) it is more readable, I'd suggest the following patch.

I will send its MLB equivalent.  I've double checked it, quotes have
been kept where meaningful.

I'd like to stress that I'm a bit afraid with the following line from
libtool.m4, which I refused to alter.  But this line stinks.

  file_magic_regex="`expr \"$deplibs_check_method\" : \"file_magic \(.*\)\"`"

It should be

  file_magic_regex=`expr "$deplibs_check_method" : "file_magic \(.*\)"`
