No personal information is stored by TextMate itself.
The “invisible” part of the document (i.e. not directly visible as text in the editor) are bookmark positions, state of foldings (what part of the text is folded), and the carets position.
If the file is transferred to a non-HFS+ file system this is what often ends up as the ._«filename» file.
