PDF/.ai import: the PostScript file error names File › Open and File › Place, which read the file

document.pdfInfo and clipboard.importPdf, given a PostScript file (an
EPS, or an .ai in an older PostScript format), failed with "this is a
PostScript file (...), which can't be opened yet: save it as PDF,
PDF-compatible .ai or SVG". document.open and file.place read the same
file through the EPS reader. The error told users to convert a file that
VectorCraft opens.

The error now says the file is not a PDF and that File › Open and
File › Place read it as EPS. The 13 catalogs that carry the message get
the new text.
