Incorrect "root" and "sqrt" symbols using TeX fonts

[Stephan Pabst]

Hello,

using lout 3.12 with TeX fonts (from lout.teq.2.2.tar.gz),
the "root" and "sqrt" symbols are displayed incorrectly.
An ASCII drawing might give an impression of what happened:


    @SysInclude { eq }     @SysInclude { teq }
    ...                    ...
    @Eq { sqrt x }         @Eq { sqrt x }

           __                     __
       _  /                      / 
        |/ x                      x


The following unified diff shows my modification of
$(LIBDIR)/include/teq which solved the problem:

However, two questions remain:

- Is this modification a bug fix, or is it just a workaround which
  will fail under certain circumstances?
- If it is just a workaround, what is the proper solution to this
  problem?

Thanks in advance.
