Frog creates invalid FoLiA

[kosloot]

consider the following document:

<FoLiA xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://ilk.uvt.nl/folia" xml:id="strbug" generator="libfolia-v1.14" version="1.5.0">
  <metadata type="native">
    <annotations>
    </annotations>
  </metadata>
  <text xml:id="strbug.text">
    <p xml:id="p.1">
      <t>Chipssnijden</t>
      <str xml:id="str.1">
	<t>Chipssnijden</t>
      </str>
    </p>
  </text>
</FoLiA>

it contains an obsolete Dutch ij ligature.

Frog will handle this file replacing the ij by ij which is wrong.
Replacing should only be done when there is a '--outputclass' specified different from the '--inputclass' (which is "current" here)

In this case 'inputclass' and 'outputclass' are not specified, so both are "current" but that is interpreted wrong apparently.
This yields the erroneous document:

</FoLiA>

In this document the 'deeper' text Chipssnijden from the Word, does not match the Chipssnijden from the Paragraph, as folialint points out:

inconsistent text: node p(p.1) has a mismatch for the text in set:current
the element text ='Chipssnijden'
the deeper text ='Chipssnijden'

Ok, the problem was quite obscure:
frog -x filename.xml -X out.xml
DID work correctly

BUT
frog -X out.xml filename.xml
DIDn't

The reason being that, when frog detects an XML file by its extension, it didn't check whether inputclass was the same as outputclass .
When using -x, fo force XML input, this WAS checked.

Fixed now.
