Ian Lance Taylor Dec. 2, 2011, 7:27 p.m. UTC 
This patch to the libgo script merge.sh does the following:

* Permit specifying a revision on the command line.

* Add various new C files to the merge, reflecting their addition to the
  library.

* Automatically converts the Unicode character · used in the master
  library C code to _ before merging, avoiding a lot of pointless
  conflicts.

Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline.
