Fix empty ini handling

[pdelre]

When XdebugHandler comes across an empty ini file, it report a Unable to read ini error. This appears to be caused by loose type matching when calling file_get_contents.

The result of this error, in particular, causes composer to not restart itself with xdebug disabled.

Many thanks for this.

The original idea was that you were unlikely to have a totally empty ini because they usually contain something, even if it is commented out. And having one would indicate something wrong with your setup.

However perhaps that approach was too strict.

Thank you for the merge. Indeed, I did discover this due to a bad configuration setup.

Is there a release process I could assist with? I just realized my PR didn't update the Unreleased section of the CHANGELOG. I'd be happy to assist with any additional code changes that makes it easier to cut the 1.4.1 release.

No worries about updating the CHANGELOG as I'll do that prior to cutting a new release. I tend to wait a week or two in case something else pops up.

It would be great to have this release done in time to have it included in composer 1.10.0 stable. :)
