Tom Tromey 8e0d0b9741 Bug 1350097 - handle very long floating point output in cvt_f; r=froydnj
Bug 1350097 points out a case where the assertion in cvt_f, added in
https://bugzilla.mozilla.org/show_bug.cgi?id=1060419#c127, triggers.
Before this addition, code calling this printf variant would end up just
printing something invalid, as the truncated value would be emitted.
This patch increases the buffer size to be sufficient for DBL_MAX.
