[nongnu] elpa/rust-mode 7960c74 417/486: Do not allow subword-match when detecting built-in formatting macros

[ELPA Syncer]

branch: elpa/rust-mode
commit 7960c74d4f575fec7b0b435a86f8f07594f24f9f
Author: Dato Simó <dato@net.com.org.es>
Commit: Nathan Moreau <nathan.moreau@m4x.org>

    Do not allow subword-match when detecting built-in formatting macros
    
    Before this change, a user-created macro like ‘cprintln!’ would see the
    ‘println’ subword highlighted as a built-in macro, and the leading ‘c’
    left without color.
    
    After this commit, only full words will be recognized as built-ins, and
    ‘cprintln!’ is highlighted as a regular macro in full, not as a built-in.
    
    In addition, this commit fixes the same issue for the write! macro.
