I ran into another problem with the trailing 'M' from svnversion
when doing 'make rinstaller' in R_HOME/src/gnuwin32:
   E:\R\R-svn\r-devel\src\gnuwin32\installer>type R-2.8.0dev.log
   Inno Setup 5 Command-Line Compiler
   Compiler engine version: Inno Setup 5.2.3 (ISPP
   [ISPP] Preprocessing.
   [ISPP] Preprocessed.
   Parsing [Setup] section, line 10
   Parsing [Setup] section, line 20
   Error on line 12 in e:\R\R-svn\r-devel\src\gnuwin32\installer\R.iss: Value of [Setup] section directive "VersionInfoVersion" is invalid.
   Compile aborted.
The offending line 12 in R.iss is
    12  VersionInfoVersion=
and it is put there by src/gnuwin32/installer/JRins.pl.
The following patch removes possible the trailing M or S
from the svn version number when making the Windows installer.
With that change 'make installer' completes without error
and I can run the installer (and uninstaller) successfully
with a locally modified svn tree.

It is nice to be able have the svn version available in R
and the 'M' (modified) tag is useful information.  It would
be more useful if we also stored the output of 'svn diff'
in the binary distribution, so we could tell exactly what was done.
