* lib/error.c (__error_at_line): Fix ';;'.

Pushing as trivial.

Noticed this while writing a syntax check rule to look for bogus
doubled semicolons.  If there's interest, I could add this rule
to maint.mk:

# Except for shell files and for loops, double semicolon is probably a mistake
sc_prohibit_double_semicolon:
        @prohibit=';;'                                          \
        in_vc_files='\.[ch]$$'                                  \
        exclude='for \(.*\)'                                    \
        halt="Double semicolon detected"                        \
          $(_sc_search_regexp)
