Thanks! Applied in revision 708; I tested from a clean slate this
time (see my recent mail regarding revision 703). We usually don't
repeat the filename in the log message, so I tweaked that.

By the way, I got a little confused by the name of the macro
SVN_SEARCH_NEON -- it's not actually searching for neon, but rather
getting the neon configuration info by running `neon-config', right?
The actual locating of neon appears to be done by SVN_LIB_NEON.

Perhaps "SVN_NEON_CONFIG" or something would be better?

Haven't changed it, wanted to run the thought by you first.
