If I have branch A, then branch off it with B, and then branch off B with C, I want to know what happens if branch B is reintegrated to A before C is reintegrated to B. So, to clarify what I mean (and your answers):
A--r10--r11--r14------r17--r20--r22
\ \ \ ^
v v v /
B---r13---r15--r18--r19
\
v
C--r16---r21
If I really don't want to "update" C with A (or B), or resurrect B to allow reintegrate from C to B to A, will a simple merge from C to A work?
cd ^/branches/A
svn merge ^/branches/C
i.e. will recorded mergeinfo result in svn simply trying to apply r16 and r21 to A, which is what I want (I think)?
