make tag weirdness

[Gianluca Sforna]

Is it just me, or the "make tag" command behaved strangely in this case ?

[giallu at hal9001 devel]$ make tag
cvs tag  -c mantis-1_0_6-2_fc7
? clog
? mantis-1.0.6
? mantis-1.0.6-1.fc7.src.rpm
? mantis-1.0.6-2.fc7.src.rpm
cvs tag: mantis-httpd.conf is locally modified
cvs [tag aborted]: correct the above errors first!
make: *** [tag] Error 1
[giallu at hal9001 devel]$ mv mantis-httpd.conf mantis-httpd.conf.new
[giallu at hal9001 devel]$ cvs update
? clog
? mantis-1.0.6
? mantis-1.0.6-1.fc7.src.rpm
? mantis-1.0.6-2.fc7.src.rpm
? mantis-httpd.conf.new
cvs update: Updating .
cvs update: warning: mantis-httpd.conf was lost

[giallu at hal9001 devel]$ make tag build
cvs tag  -c mantis-1_0_6-2_fc7

I mean, the tag is NOT there, since the pre tag check failed, but it
seems that now "make tag" believes otherwise.

What am I missing?
