Yes, in general it is possible to use apr_psprintf() to transform numbers to
strings using the SVN_REVNUM_T_FMT format string and use that string for a
%s format specifier in the destination string.

An example:

   SVN_ERR_W( ... some code ... ,
              apr_psprintf("Error committing r" SVN_REVNUM_T_FMT "\n",
                           revision, pool));

becomes:

   SVN_ERR_W( ... some code ... ,
              apr_psprintf("Error committing r%s\n",
                           SVN_REV_TO_STR(revision, pool)));

where:

#define SVN_REV_TO_STR(rev, pool) apr_psprintf(SVN_REVNUM_T_FMT, rev, pool)

The case demonstrated above is a static initializer though so that this
scheme does not apply.

bye,

Erik.
