.texi.info rule

[Bruce Korb]

I edited in the "set -x ; " so I could see what actually happened when 
the scriptlet ran. Since the "top_srcdir" is ../../.., it goes into the 
source tree's "doc" directory and tries to make a backup directory. That 
doesn't work in "make distcheck". Also, "complexity.texi" is in the 
build directory, not in the source directory. This code is completely 
wrong to assume that it has to be in the source tree. Not all .texi 
files are of necessity hand edited.

.texi.info:
    set -x ; $(AM_V_MAKEINFO)restore=: && 
backupdir="$(am__leading_dot)am$$$$" && \
    am__cwd=`pwd` && $(am__cd) $(srcdir) && \
    rm -rf $$backupdir && mkdir $$backupdir && \
    if ($(MAKEINFO) --version) >/dev/null 2>&1; then \
      for f in $@ $@-[0-9] $@-[0-9][0-9] $(@:.info=).i[0-9] 
$(@:.info=).i[0-9][0-9]; do \
        if test -f $$f; then mv $$f $$backupdir; restore=mv; else :; fi; \
      done; \
    else :; fi && \
    cd "$$am__cwd"; \
    if $(MAKEINFO) $(AM_MAKEINFOFLAGS) $(MAKEINFOFLAGS) -I $(srcdir) \
     -o $@ $<; \
    then \
      rc=0; \
      $(am__cd) $(srcdir); \
    else \
      rc=$$?; \
      $(am__cd) $(srcdir) && \
      $$restore $$backupdir/* `echo "./$@" | sed 's|[^/]*$$||'`; \
    fi; \
    rm -rf $$backupdir; exit $$rc
