calc function not compiling correctly

Description

When compiling LESS to CSS, the calc function is not working correctly.

Steps to recreate

1. in a LESS file, add a line like this width: calc(50% - 20px);
2. when you compile, you'll see the generated output is like this: width: calc(30%);
3. it is supposed to retain the original calc but it looks like it's actually trying to subtract 20 from 50%

Current behavior

It's not supposed to modify what is in-between the parentheses of the calc function

Expected behavior

the text between the parentheses is supposed to be retained.

apparently this is a known issue with some compilers using a version of LESS lower than 1.4
