[Rd] Customizing width of input in Rterm

[Iago Giné-Vázquez]

Hi all,

When using Rterm.exe (on Windows, I didn’t check Linux) only a limited 
number of characters is displayed in the input lines, independent on the 
|width| option, and, when navigating through the command history this 
becomes very uncomfortable, since a command is not fully displayed and, 
for example, it is very difficult to know which parts of a command are 
being edited.

I know, using Linux you can avoid using Rterm. And using Windows, the 
first option is RGui. However, Rterm is the default for some editor/IDE 
plugins/extensions, such as NVim-R for ViM or also for VS Code. In fact, 
searching on the web for the reported issue, I found it reported several 
times to the R extension plugin for VS Code.

Would it be possible to allow longer lines to be displayed, at least to 
the terminal width, or to customize the number of columns displayed?

Thank you for your time and for maintaining R, it’s a great work!

Best regards,

Iago
