Beware. First, this kind of optimization would bring very small gains in
my setup. Second, it's dangerous: if you only refresh ls-R files for
TEXMF trees where files are installed by the *latest* version of the
package, you'll miss the necessary refreshing of TEXMF trees containing
files from the *previous* version of the package. For instance, if the
previous version shipped a file in some TEXMF tree and the current
version puts the same file in another TEXMF tree, then the kind of
optimization mentioned above will lead to the ls-R files for *both*
TEXMF trees to reference the file, whereas only one of them actually
contains it.
