In progs.tex, change label of wild and regex to bwild and bregex,
respectively.

In fileset.tex, fix cross-references (the ilink usage was reversed).
And use bwild and bregex for cross-referencing to point to
specific part of chapter (as seen in other places referencing the Utilities
chapter).

I saw these several undefined cross-references in latex log.

Also fix redundant "estimate command command" references.
