@w{text}: Prevent Line Breaks

@w{text} outputs text and prohibits line breaks within text.

You can use the @w command to prevent TeX from automatically hyphenating a long name or phrase that accidentally falls near the end of a line.

You can copy GNU software from @w{@file{prep.ai.mit.edu}}.

produces

You can copy GNU software from `prep.ai.mit.edu'.

In the Texinfo file, you must write the @w command and its argument (all the affected text) all on one line.

Caution: Do not write an @refill command at the end of a paragraph containing an @w command; it will cause the paragraph to be refilled and may thereby negate the effect of the @w command.
