Just to summarise on this, you are getting blank paragraphs because the 
paragraph is not being hidden because the paragraph is part of your 
document. Only the text within the paragraph is being hidden.

To hide the paragraph, it must be generated by your macro and not in the 
document tree. A macro cannot generate a newline or start a new 
paragraph. A macro can emit paragraphs as part of a "document" tag so 
you could introduce multiple paragraphs where there was one paragraph, 
but your macro would still be inserted into a top level document paragraph.

If you insert your document inside a concat (as you have been) you will 
get long up-wrapped lines and a multi-paragraph (with short lines) will 
look even funnier - for what will happen, the dudas while by typeset to 
make a block, and within the concat that block will be set as if it were 
a single character - as a rect.

Therefore your solution is either to stop texmacs typesetting blank 
paragraphs or pas the dudas comments to a macro along with the preceding 
paragraph to the same macro - i.e. a macro which takes some text AND the 
dudas.

Maybe we can mix these ideas:

<new-remark|dudaux|Duda>

<assign|dud-true|<\macro|x|d>
<arg|x>

<compound|dudaux|<arg|d>>
</macro>>

<assign|dud-false|<\macro|x|d>
<arg|x>
</macro>>

<assign|duda|<macro|x|d|<compound|<merge|dud-|<value|mostrar-dudas>>|<arg|x>|<arg|d>>>>

<assign|mostrar-dudas|true>

<duda|blag sfdg asdg sadg sdablah|dusfdag sfdg .a,sfd sdf sd agf s dg s g,
asdg askdmgf ajksdhgf ;sajkld;ghasdlkgjh sadgsahd gkljs ads>

So this works by choosing which document tree duda will expand to - one 
has two members and one has only one member. But it means that the duda 
value and the previous text should be an argument to the same macro.

If you want more than one duda, then remove <duduax|<arg|d>> and replace 
with <arg|d> and then use dudaux directly in your document (as the 
second argument to the duda macro)
