This macro takes as its argument the name of a buffer containing
substitutions, one per line, in the form <old><new>.
It starts applying those substitutions to the current buffer.
It exits when you exit any query replace, leaving C-. set up
as a continuation macro to resume the query replace sequence at
the query replace which was exited.
If given numeric arg, then Replace String without querying.!

!Tags Multi Query Replace:! !C Perform multiple replacements on many files.
Given as an argument the name of a buffer containing
a list of replacements a la Multi Query Replace,
we process the first file in the current tag table
and set C-, to a macro to process the next file.
If this macro or C-, given numeric arg, then Replace String without querying.!
