[elpa] externals/dash cec8c0d 311/316: Rename approx-equal to more accurate approx=

[ELPA Syncer]

branch: externals/dash
commit cec8c0d6850e132ba7f33fbe403cb69e2793879e
Author: Basil L. Contovounesios <contovob@tcd.ie>
Commit: Basil L. Contovounesios <contovob@tcd.ie>

    Rename approx-equal to more accurate approx=
    
    * dev/dash-defs.el (approx-equal): Rename...
    (approx=): ...to this, to more accurately reflect its function.
    All references changed.
    
    * dev/examples.el (-fixfn): Clean up examples.
    * README.md:
    * dash.texi: Regenerate docs.
